AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
2,4-Difluorophenol, 2,5-difluorophenol, 2,3-difluorophenol, 3,5-difluorophenol, 3,4-difluorophenol, 2,4,5-trifluorophenol and 2,3,4-trifluorophenol were converted into all 18 possible di- or trifluorinated hydroxybenzoic acids, all of them new compds. The ...
UMR 7139 CNRS, Universite Pierre et Marie Curie and Laboratoires Goemar, Station Biologique, Place Georges Teissier, F-29680 Roscoff, France. weinberg@sb-roscoff.fr Gametophytes of the marine alga Chondrus crispus are more resistant than tetrasporophytes t ...
Oxygen is a key substrate in animal cell metab. and its consumption is thus a parameter of great interest for bioprocess monitoring and control. A system for measuring it based on an oxygen balance on the liq. phase was developed. The use of a gas-permeabl ...
The gas phase species produced in rf plasmas of hexamethyldisiloxane (HMDSO), Si2O(CH3)(6), diluted with oxygen, have been investigated. The complementarity of Fourier transform infrared absorption spectroscopy and mass spectrometry allows the determinatio ...
A method using O-alkylguanine-DNA alkyltransferases (AGT) is disclosed for transferring a label from a substrate to a fusion protein comprising the AGT. This allows the detection and/or manipulating of the fusion protein, both in vitro and in vivo, by a ...
2,3-Dichloropyridines undergo a mono- or a dicarbonylation in the presence of carbon monoxide, an alc., and a palladium catalyst, affording selectively either alkyl 3-chloropyridine-2-carboxylates or dialkyl pyridine-2,3-dicarboxylates in good yields, depe ...
The solubility of carbon monoxide in 37 ionic liquids and in some organic solvents has been determined using high-pressure C-13 NMR spectroscopy; a method for predicting the CO solubility is demonstrated, and it was shown that the rate of the hydroformylat ...
Using a density functional approach, we determine the relative stability of various oxygen species in alpha -quartz. We considered interstitial species in the form of atomic and molecular oxygen, as well as network species, such as peroxyl and ozonyl link- ...
According to Khan et al. [Khan, A. U., Kovacic, D., Kolbanovskiy, A., Desai, M., Frenkel, K. & Geacintov, N. E. (2000) Proc. Natl. Acad. Sci. USA 97, 2984-2989], peroxynitrite (ONOO(-)) decomposes after protonation to singlet oxygen ((1)Delta(g)O(2)) and s ...
Photoinduced phenomena are of general interest for new materials. Recently, photoinduced molecular desorption of oxygen has been reported in carbon nanotubes. Here we present, using thermopower measurements, that carbon nanotubes when exposed simultaneousl ...
